Re: [Zope] Python Script REQUEST namespace not found.

5 Sep 2002

      this is interesting to know that there is a magic around ZPublisher.
But I believe, there must be a definite answer to get Python Script reading
variable in REQUEST namespace.

I tried using Session object and it works.

Below is my code:

---------------------------
DTML-document: helloDoc

<dtml-call "SESSION.set('name', 'john') ">
<dtml-var hello>

---------------------------------
Python Script 'hello'
Parameter name='world'

session=context.REQUEST.SESSION
l=session['name']

return "Hello %s" %l

----------------------------------

The result is: 'hello john' which is correct result.

I'm trying to write my first python script by passing parameter through
the
REQUEST object as following:
---------------------------
In the Python Script:
Parameter: name="world"
return "Hello %s" %name
------------------------
in my DTML-Document:
<dtml-call "REQUEST.set('name', 'John')">
<dtml-var hello>
Parameters are only magically passed into Python scripts when they
are called directly from the Web (this is ZPublisher magic)
or when they bind (--> "Bindings" tab) the DTML namespace (this is
DTML magic).
When possible, you should not rely on magic, but pass the parameters
explicitly:
<dtml-var expr="hello('John')">
